Does anyone know if the bottlecap transistor on the old midway PS control the +5 capped one but the regulated +5 seems to move as the game warms up. I haven't replaced that trasistor yet and thought maybe it was overheating.
 
Anything's possible, but that would be very unusual. It (could) be the pot. Did you replace all the caps?
